AMR Adaptive Multi-Rate is a compressed audio file format used for storing audio data encoded with the patented Adaptive Multi-Rate audio codec. The format was originally introduced and popularized by the Ericsson corporation, but can now be found on every modern mobile device. The EVS codec also provides enhanced interoperation with the AMR-WB codec over all nine operational bit-rates. When the EVS codec is supported, the EVS AMR-WB Inter-Operable mode may serve as an alternative implementation of AMR-WB codec.

  1. Compared to narrowband speech codecs like AMR optimized for traditional telephone voice quality of 300-3400 Hz, the AMR-WB codec's wider bandwidth of 50-7000 Hz provides excellent speech quality. Although AMR-WB pre-dates AMR-WB, it is more constrained and is therefore treated as a subtype of AMR-WB at this Web site; Comments welcome.
  2. AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband AMR-WB. G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB.
